After you enable the BGP ORF capability, the local BGP router negotiates the ORF capability with the
BGP peer through Open messages (that is, determine whether to carry ORF information in messages;
if yes, whether to carry non-standard ORF information in the packets). After completing the negotiation
process and establishing the neighboring relationship, the BGP router and its BGP peer can exchange
ORF information through specific Route-refresh messages.
For the parameters configured on both sides for ORF capability negotiation, refer to
.
Follow these steps to enable the BGP ORF capability:
